The valve l2 is lpositioned directly above the"- inleti' passage and is movedi downwardly toclose said; inlet passage when the ga'solene M s p a within the enlarged portion 4 of the supplyg a. seetional leyapio of my I A main lock casing 14 is secured by bolts 15 and nuts 16 (see Fig. 2) to the body portion 1, and has a passage 17 which registers with the inlet passage 3. This passage 17 leads to a frusto-conical bore 18 in themain lock casing 1%, there being a main inlet passage 19 in the casing'liwhich also com' municates with the frusto-conical here 18. This main inlet passage 19 is connected with the source of supply. A sleeve valve 20 fits Within the bore 18, and has ports 21 and 22 which when said valve is in the position shown in Fig. 1, register respectively with the main nlet passage 19 and the passage 17. The sleeve valve 20 is internally bored to receive a tapered or frusto-conical central valve 23. This valve has a ,zigzag passage 24 extending transversely thereof, the ends of said passage intersecting vthe outer surface thereof, and designed when said latter valve {is moved in the position shown in Fig. 1, to

register with the ports 21 and 22, so that when the parts are in the position illustrated, gasolene or other fluid may pass inwardly through the inlet passage 19, port 21, passage 24, port 22, passage 17 and nlet passage 3 to the supply chamber 2 of the carbureter.

The sleeve valve 20 is provided with an annularly extending flange 25 which has an annular recess 26 and an upwardly projecting pin 27, said pin being fixed within the flange 25 and passing upwardly through said annular recess 26.

An operating disk 28 has an annular projection 29 on its bottom surface which fits within the recess 26, and a series of holes 30 each of which is of similar contour and designed to be fitted over the top of the pin 27 as illustrated, there being ten holes 3Q.

The upper surface of the disk 28 has ,a number of indicating characters as illustrated, being represented by the numerals l to 9 and 0. Each one of these indications is directly above one of the holes 30, and there are a series of notches 31 in the pe riphery of the disk 28, there being one notch for each indicating mark. These notches are designed to be engaged by the end of a retainingspring 32 which is secured to .the top of the main casing 14:.

The central valve 23 is reduced in diameter at 33, thereby forming a stem which projects through ,an opening the disk 28, and is provided with an annularfiange This flange 3% has a pin v35 projecting upwardly therefrom, said pin being [designed to engage any of a series of holes 36 in .the lower faceofa disk 37,, these holes ibeing'of similar construction to the holes 310 in the disk28, there also being ten holes 36.

The upper surface of the disk .37 is prod d-with in i ati g mark si r t the e described in .s gnaent cn with the diskZfi, and

retaining the disks 28 and 37 in proper position, also act as indicating pointers, so that a person can tell at .a glance when the several elements are in the desired position.

A thumb screw 40 extends through the disk37, and engages a threaded opening in the central valve 23, the purpose of said thumb screw being ,to secure the disk 37 to the annular flange 35L.

h M1 2 ha s tr la i to h P rtZl and the :pin 35 has a set relation :t0 the ends of the passage 24. In the same manner, each of the retaining springs .32 and 39 has a se ,1'ela 11 t0 the nmin inlet p ssage 9 and the passage 17, so that since these relations are known, the disks 28 and .37 may be mo e int d ff en p s ti ns t s t e combination, and to one who knows the ,relations o hese lemen s one t h 't '.,a 1 he pas ges m y h m ved nto nem nh aft r h y hav e n moved out 10f alimement, to secure the proper alining of {the several passages and ports to permit the gas-olene or other fluid to .tlow through the inlet 19 into the supply chamber 2.

The lower-end of the central valve 23 has a threaded end .41, provided with a nut e2. This nut engages washers 13 and ski, the washer 44: being sufiieiently large to .cover the bore 18, thereby preventing any longi-.

tudinal movement between the valves and casing {151. V I

The .central valve 23 is grooved or provided with a "fiflat as vdearly shown at e5 in Fig. 3, and the sleeve valve 20 is slotted throughout-a portionof its circumference as shownatlG, said slot 16 and groove 15 being in register when the passages and ports are in alinement as above described.

A plunge 4 ha a ongue :4 w i is provided ,withcamedges 49 which normally project through the slot a and engage the flat cam provided by the groove 45 (see 3.) The plunger 4:7 is backed by an expansion spring 50, which engages the forward face of the body portion 1. This plunger 4;? also has .astein 1'51 of small diameter, and this stem is slidable through the body portion 1 and provided with a tapered end This tapered end 52 forms ,avalve, and ,is designed when the plunger and stem ,Ihl'iare moved longitudinally, to engage the valve seat 9 ,of :the intak Passage 7 which leads to .the anixing chamber, thus closing said n ak P 1$$3g ml :P-lWQ-m ng the as leae or other liquid from passing from the sup- P y hamb to t e m ing a e I The t r un ed dg f th 'ends 9 the sl t a ar s arranged w th a 1 9 l dgesyw en' he salv the.
